What is the general electron configuration for alkaline earth metals?
2 electrons in the outermost shell.
Which alkaline earth metal is the most likely to attract an electron pair?
The electronegativityÊ of alkaline earth metals decreases as you go down the group due to increase in atomic radius. The earth alkaline metals are beryllium, magnesium, strontium, barium and radium. Radium has the smallest electronegative.
Why alkali metals are more reactive than alkaline earth metals?
All atoms want to do is make their valence shell full. In alkali metals they have all of their shells completely full except one valence electron. The alkali metals REALLY want to get rid of that electron, so they will react with many elements/compounds to get rid of that electron. In alkaline earth metals they have all of their shells completely full except for two valence electrons. They also want to get rid of those electrons but the alkaline earth metals are not as desperate to do so as the alkali earth metals which make the alkaline much less reactive than the alkali metals.
Alkali metal and alkaline earth metal have how many ionization energies?
Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy
Write the expected ground-state electron configuration for the alkaline earth metal after radium?
You think probably at Unbinilium (120Ubn) an element not still obtained. The supposed electron configuration of Ubn will be [Uuo]7s2.
Is krypton a alkaline earth metal?
It is not an alkaline earth metal it is a noble gas
Is Krypton a alkaline-earth metal?
It is not an alkaline earth metal it is a noble gas
What alkaline earth metal has more protons then argon but less protons then krypton?
This chemical element is calcium (Ca).
What alkaline earth metal has the largest electron affinity?
Barium has the largest electron affinity among the alkaline earth metals.
Do all alkaline metals have 2 electron shells?
No. All the alkaline earth metals have 2 valence electrons, meaning they have two electrons in the outermost shells. No two alkaline earth metals have the same number of electron shells. Beryllium is the only one with two shells.
What element is an alkaline earth metal whose electron configuration ends in 6s2?
All alkaline earth metals have electron configurations ending in s2; 6s2 would be the alkaline earth metal in period 6 of the PTE, which is barium.
What characteristic does the alkali metals alkaline earth metals and the halogens have in common?
All alkali metals, alkaline earth metals, and halogens have a common valence electron configuration: alkali metals have 1 valence electron, alkaline earth metals have 2 valence electrons, and halogens have 7 valence electrons. This shared electron configuration influences their chemical properties, such as reactivity and bonding tendencies.
Look at the periodic table. What is the charge on any ion formed by an alkaline earth metal?
The charge on any ion formed by an alkaline earth metal is typically +2. This is because alkaline earth metals readily lose two electrons to achieve a full outer electron shell and acquire a stable electron configuration.
What is the general electron configuration for alkaline earth metals?
2 electrons in the outermost shell.
What is the important characteristic do the alkali and alkaline earth metals have in common?
they all have at least one electron
What is the charge on any ion formed by a alkaline earth metal?
The charge on any ion formed by an alkaline earth metal is typically +2. Alkaline earth metals have two valence electrons that they can lose to achieve a stable electron configuration, resulting in a 2+ charge.
Which alkaline earth metal is the most likely to attract an electron pair?
The electronegativityÊ of alkaline earth metals decreases as you go down the group due to increase in atomic radius. The earth alkaline metals are beryllium, magnesium, strontium, barium and radium. Radium has the smallest electronegative.
